摘要
The coaxial floater and buoy on the surface of fluid compose a point absorber wave device. The hydrodynamic fluid/solid interaction becomes more complex due to relative heave motion. In order to investigate influencing factors of wave energy device efficiency, This paper aims at presenting the heaving mode hydrodynamic coefficients and exciting force of the wave energy device by using the coupling hydrodynamic analysis method and establishing heave coupled motion equation of the device by considering spring factors of the Power Take Off (PTO) system. The hydrodynamic coefficient and capture width ratio (CWR) of the wave energy device for various geometrical configurations are presented and discussed. Comparing the calculation and experimental results for the heave amplitude response operator and device energy conversion efficiency.
